Multiple TH in rows?

donino

Hi,

I am currently trying to embed datatables in a BIRT report viewer. The result is already awesome, complex headers are perfectly processed! I encounter an issue with tables wich have multiple 'TH' in rows. For example BIRT generates this kind of markup, if we have two dimensions in rows in a crosstable:

When i invoke dataTables i get: [quote] Uncaught TypeError: Cannot call method 'fnSetData' of undefined [/quote]
If i remove the second TH on each row it works. Is it known issue? Any possible workaround? Thanks!

Well, i answer to myself! It appears with all my handlings in the sample file i accidentally removed 'colspan="2"' in thead and tfoot, both on the first column. Now it works, though it seems dataTables is a little bit confused by the difference of column numbers between header and rows. I get this exception:

[quote] Uncaught TypeError: Cannot read property 'style' of undefined [/quote]

on the line:

[quote]
else if ( oColumn.bVisible )
{
nThs[i-iCorrector].style.width = "";
}
[/quote]

It does not look so bad since all features work as expected. I should be able to post a live demo link soonly if some people are interested, the combo BIRT+Datatables is amazing!

Yes, the colspan=2 in the header would cause issues. DataTables can use colspan / rowspan in the header, but each column must have its own unique cell in the header so sorting etc can be applied. For example: http://datatables.net/release-datatables/examples/basic_init/complex_header.html
